1 D code for FDTD in matlab

在matlab环境下实现自相关与功率谱密度的计算()

This is a z transform based watermarking algorithm used for copy right protection

说明：  非线性问题的线性拟合问题的源程序 非线性问题的线性拟合问题的源程序用MATLAB实现(nonlinear fitting a linear source of the nonlinear fitting the linear source with MAT LAB realization)

均匀介质二维声波数值模拟，采用clayton-engquist 1阶边界条件。有公式及参考文献。带有速度模型以及雷克子波函数，解压后直接运行就可以(2D acoustic numerical simulation of a homogeneous medium, using the clayton-engquist 1-order boundary conditions. Formulas and references. With the velocity model and the the Ricker wave function, and can run directly after decompression)

this simulationto make table

说明：  求解分岔问题，非常适合于求解非线性振动问题(Solving bifurcation problems)

Inverse Z Transformation using Matlab

基于DWT的数字水印嵌入算法，已进行过调试，可以直接使用(DWT-based digital watermarking algorithm, has been commissioning, can be used directly)

说明：  对原始噪声图像进行空间域图像增强,对比通过加法，减法，乘法，除法，对数变换，灰度变换，线性滤波，直方图均衡，中值滤波等算法的实现效果(Noise on the original image space domain image enhancement, contrast through the addition, subtraction, multiplication, division, logarithmic transform, gray level transformation, linear filtering, histogram equalization, median filtering algorithm results)
